Sometimes being the villain is way more fun than being the hero.

Mamori Wataya is used to being a nobody. She lingers in the shadows of her high school, dismissed by everyone around her-that is, until she meets Soshi Fuji, the school's notorious troublemaker. Fueled by her deep admiration for villains, Mamori quickly becomes captivated by Fuji's devil-may-care attitude, and together they embark on a rebellion against the status quo.

After a stay in the hospital, Fuji returns to school with a new prank in mind: outperforming Koichi on an upcoming test! Confronted by this seemingly insurmountable task, Fuji ropes in the pair's charismatic classmate Kei to tutor Mamori. But when Kei develops a fondness for her new pupil, she sparks a rivalry with Fuji as both of them fight for Mamori's affections!
